Computer overheating

this could be an issue with your psu, a friend of mine was experiencing constant crashing from upgrading his gpu and running it on the old psu, 500watt and above is reccomended for most modern gpu's.. what do you have ?

With a new card and an old processor you are suffering also from bottle-necking. Picture an aircraft and a 10 inch pipe. The carrier is your GPU and the pipe is your CPU. The carrier can't fit through the pipe. Like pilot said you will need to upgrade the other components. Your computer will only run as fast as the slowest part.

EDIT: Does run for roughly the same amount of time then crash? eg 10mins then crash every time? If yes then its probably a GPU overheating problem if no then it's probably the PSU

It seems only to crash when the room is relatively warm about 20-25 degrees. It would take about 30 mins to crash but i have been running it for a good hour and a half now with a cool room and its averaging 30 degrees on the CPU so i think it might be gone now. However, today we did reverse my rear fan so its quickly sucking air out, apparently 1330spm on the fan at medium and is on alert for high speed. My dad is going to take it to work and change the CPU to a newer one and possibly change the power supply.

bottlenecking shouldnt cause his pc to crash just run shitty.. bf3 is alot more GPU intensive than CPU intensive theres an article i read that showed the game pretty much ran the same on an I7 as it did on a dual core I3, but changing the ram and gpu had major effects on the games playability. i think your right about the GPU overheating or PSU problem, although it says the minimum required PSU for the radeon 6770 is 450watts usually a 550watt psu is needed for modern GPU's. good luck man hope you get it sorted theres nothing more annoying than PC problems.
